问题

Hi I need some thing like below image

I have implemented the code but its just auto populate like

I am not able to populate the result. I have implemented the google code as below

<script>

(function () {
    var cx = '011189415628571362123:google';
    var gcse = document.createElement('script');
    gcse.type = 'text/javascript';
    gcse.async = true;
    gcse.src = 'https://cse.google.com/cse.js?cx=' + cx;
    var s = document.getElementsByTagName('script')[0];
    s.parentNode.insertBefore(gcse, s);
   })();


<gcse:search enableautocomplete="true"></gcse:search>

What I need is instant result like google shows

The following CODE snippet will populate result on every keystroke. Click Run code snippet button & then click Full Page button for a better view & then check to see if it satisfies your requirement. It uses Google Custom Search element control API. Study that document for further customization.

(function($, window) {
  var elementName = '';
  var lastSearchTerm = '';
  var initGCSEInputField = function() {
    $( '.gcse-container form.gsc-search-box input.gsc-input' )
      .on( "keyup", function( e ) {
      if( e.which == 13 ) {
        // 13 = enter, execute custom CODE as necessary on enter
        console.log("Enter detected");
      }
      else {
        if( elementName == '' ) {
        	// assuming that we have only one search element on the page
        	var elements = google.search.cse.element.getAllElements();
          for( var element in elements ) {
            elementName = element;
            if( elementName != '' ) {
            	break;
            }
          }
        }
        if( elementName != '' ) {
        	// searching on each keystroke
          var searchTerm = $.trim( this.value );
          if( searchTerm != lastSearchTerm ) {
            // console.log( searchTerm );
            google.search.cse.element.getElement( elementName ).execute( searchTerm );
            lastSearchTerm = searchTerm;
          }
        }
      } 
    });
  };
  
  var GCSERender = function() {
  	google.search.cse.element.render({
        div: 'gcse_container',
        tag: 'search'
      });
      initGCSEInputField();
  };
  
  var GCSECallBack = function() {
    if (document.readyState == 'complete') {
      GCSERender();
    }
    else {
      google.setOnLoadCallback(function() {
        GCSERender();
      }, true );
    }
  };
  
  window.__gcse = {
  	parsetags: 'explicit',
    callback: GCSECallBack
  };
})(jQuery, window);

(function() {
  var cx = '017643444788069204610:4gvhea_mvga'; // Insert your own Custom Search engine ID here
  var gcse = document.createElement('script'); gcse.type = 'text/javascript'; gcse.async = true;
  gcse.src = 'https://www.google.com/cse/cse.js?cx=' + cx;
  var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(gcse, s);
})();

<div class="gcse-container" id="gcse_container">
